## Description

This book is ideal for a one-semester course in business statistics, offering a streamlined presentation of Business Statistics, by Sharpe, De Veaux, and Velleman, with Excel® screenshots throughout the book.

Professors Norean Sharpe (Georgetown University), Dick De Veaux (Williams College), and Paul Velleman (Cornell University) have teamed up to provide an innovative new textbook for the undergraduate introductory business statistics course. These authors have taught at the finest business schools and draw on their consulting experience at leading companies to show students how statistical thinking is vital to modern decision making.

Managers make better business decisions when they understand statistics, and Business Statistics gives students the statistical tools and understanding to take them from the classroom to the boardroom. Hundreds of examples are based on current events and timely business topics. Short, accessible chapters allow for flexible coverage of important topics, and the conversational writing style maintains student interest and improves understanding.

Business Statistics includes Guided Examples that feature the authors’ signature Plan/Do/Report problem-solving method. Each worked example shows students how to clearly define the business decision to be made and plan which method to use, do the calculations and create the graphs, and finally report their findings, often in the form of a business memo. Every chapter reminds students What Can Go Wrong and teaches them how to avoid making common statistical mistakes.
CourseSmart textbooks do not include any media or print supplements that come packaged with the bound book.
